Valve with true and false recognition function and its ture and false identification method

Abstract

This invention provides a valve with a genuineness discriminating function and a genuineness discriminating method for the valve that easily and securely discriminate between a copy and a genuine article to prevent, for example, a copied valve from being distributed and so on. The valve with the genuineness discriminating function is characterized in that a genuineness discrimination body 6 for deciding whether the valve is genuine is provided on a handle 3 itself for valve mechanism operation or at a position of characteristic information of the valve, such as the brand name, nominal diameter, applied fluid, opening / closing direction, materials of respective parts, shape, amount, application temperature, etc., of the valve, nearby the handle 3.

Description

technical field [0001] The present invention relates to a valve with authenticity identification function and a method for authenticity identification of the valve having a function for discriminating authenticity. Valves with authenticity identification functions and valve authenticity identification methods for the circulation of product valves. Background technique [0002] For example, the imitation hazard of general valves such as gate valves, spherical valves, and float valves has become a serious problem. Imitations that cannot be easily distinguished from genuine ones tend to circulate in large quantities in overseas markets including Asia. If the circulation of imitation products is allowed, it will not only lose due benefits or reduce profits, but also damage the trust in the enterprise, so it is a very serious problem for enterprises, and it will also be harmful to users who buy imitation products. Misunderstanding of product quality has caused a lot of damage. ...

Problems solved by technology

[0008] However, for valve products that adjust the flow rate of fluid or open and close the flow path, among the parts that constitute the valve, the main body and valve cover with a large surface area are often cast or forged, so the surface has many unevenness. It is difficult to install the above-mentioned stick-type authenticity identification body on the main body or valve cover, etc.

Moreover, most of the valve products imitated overseas are general-purpose valves such as gate valves, spherical valves, and float valves with large flow rates and smaller sizes (such as 1 / 4B to 2B), so that the space for disposing authenticity and false identification bodies is limited.

[0009] As a part that is easier to stick than the surface of the casting or forging, there is a plate (specification display plate) as a stamped part made of aluminum or stainless steel, but the nominal classification, size, applicable fluid, and main structure of the valve are displayed on this plate Information about valve specifications such as material of parts, opening / closing direction display, and batch number, etc., have the function of assisting correct operation of the valve. When viewed from a specific angle, the specification information can be confirmed through the authenticity identification body, but if the authenticity identification body appears to change color depending on the angle, the specification information may not be confirmed

In addition, on a small-sized valve, the label is also small (for example, about 20 mm in diameter), so the authenticity identifier should be placed so that most of the specification information is covered. As mentioned above, when the specification information cannot be confirmed through the authenticity identifier It may also lead to misuse or misoperation of the valve
